A/C Fan Inoperative
My A/C fan will not come on in any mode. I have a 2005 Avalanche 1500 with Dual Automatic Climate Control. Two Days ago as we were on the highway, I engaged the A/C and it seemed everything was fine. The next day I turned it on and the fan would not come on. When I hit the A/C button, I can hear the compressor come on and when I switch from dash outlets to dash/floor outlets, etc. I can hear the 'flapper' move, but no fan. I have checked the front climate control blower fuse in the underhood fuse panel (it checks good). ANY IDEAS?
